I have a participatory budgeting experiment. I want each participant to choose the amounts for each federal department according to THEIR OWN values. How can I best set up the help files for each budget amount so they can? (I also have the participants choose the tax rates, but that can be more easily explained, e. g., the marginal rate that affects those earning more than $300,000 per year.) For example, our Federal Budget specifies defense at 598 billion, education at 70 billion (<a href="http:/www.nationalpriorities.org/budget-basics/federal-budget-101/spending/">as per 2015 numbers</a>) A participant might say to interchange these numbers (80 billion for defense and 800 billion for education). How could they learn what they would not get or get, respectively? How could they say that is or is not they would want if they were the proverbial king or queen?
